Abstract: To thoroughly address the issues of engine hood vibration and abnormal noise during driving, this article conducts a detailed investigation and analysis of the problem phenomena, and deeply studies the underlying physical mechanisms and influencing factors by establishing a vibration model. Based on the research results of this mechanism, a computer aided engineering (CAE) simulation model is further constructed in combination with the actual vehicle conditions. The key parameters and target values for controlling the driving vibration of the engine hood are clarified, and the effectiveness of these measures is verified. Based on the research results, the relevant enterprise technical standards are revised to effectively prevent similar problems from occurring in subsequent vehicle models.
